The referendum on October 10 will ask voters to choose between the current first-past-the-post system and a new mixed- member-proportional (MMP) one. Here's the dish on MMP:
? Voters cast two votes on one ballot, one for a local MPP as currently and one for their preferred party. The two votes can be for different parties.
? Parties need to get 3 per cent of the popular vote province-wide to qualify for at-large seats.
? Parties elect a list of at-large MPPs that is published before the election.
? The legislature consists of 129 seats: the current 103 local ridings are reduced to 90, and 39 seats for at-large party list candidates are created.
? If the number of a party's elected candidates is less than its share of the overall vote, it gets a top-up of MPPs.
